The Bushmaster C15 Carbines are a unique hybridization of traditional AR-15 type features with space-age Carbon 15 composite molded receivers for light weight and rugged durability. The Carbon 15's 14.5" M4 profile barrel is made of chrome-lined chromemoly steel and includes an Izzy flash suppressor pinned and welded in place to achieve 16" overall barrel length. The barrel and other critical steel parts are manganese phosphate finished for corrosion and rust protection. The upper receiver has a receiver length raised picatinny optics rail with an integral dual aperture rear sight that is windage adjustable while the front sight is a standard A2 post-type gas block adjustable for elevation. The Carbon 15's safety levers have color-coded markings on both sides of the receiver for quick visual check of firing condition. This rifle features a Bushmaster red dot sight, a 2-position thumb safety, and a 30-round magazine. Its stock, its metal, and its bore are all in very good condition.
